[alsa-devel] [PATCHv4] ASoC: dapm: Add new widget type for constructing DAPM graphs on DSPs.
Add some DAPM widget types to better support the construction of DAPM graphs within DSPs.
Signed-off-by: Liam Girdwood liam.r.girdwood@linux.intel.com ---
Chnages V3. o Go back to the original widget type plan and replace pipeline with scheduler widget. Changes V2. o No need for multiple types since core does not care. Changes v1. o Added some documentation. o Split codec widget into encoder and decoder to avoid confusion with HW CODECS.

The patch
ASoC: topology: Fix usage of SND_SOC_TPLG_INDEX_ALL during load
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
